GAS-GENERATING OIL-BURNER.

Application filed January 24, 1919.

To a whom. it may (OIL/(WW1 Be it known that l. EDWIN L. MILLER, a citizen of the United States, residing at bans-as City, in the county of Jackson and State of Missouri, have invented a new and useful Gas-Generating Oil-Burner, of which the following is a specification.

My invention relates to gas generating oil burners and particularly to a device of this character which is used in heating furnaces and stoves.

The objects of my invention are, first, to provide a simple and inexpensive gas generating oil burner device which may be read ily installed in furnaces and stoves, second, to provide the device with a retort having facility for self cleaning, third, to provide the device with a mixer having facility for receiving and mixing the gas from the retort with air and provided with an outlet for the mixture which is adapted for a torch flame, fourth, to provide a housing for the mixer and having a series of vent orifices for venting the gas mixture to produce a blue flame and, fifth, to provide a base for the device having facility for conserving the oil wasted through the retort.

I attain these objects and other advantages by means of the construction and combination of parts illustrated in the accompanying drawing in whichFigure 1, is a vertical section through the device constructed in accordance with my' invention; Fig. 2, is a top plan view of the housing burner, a part of my invention; Fig. 4, is a top plan view of a modified form of the housing burner; and Fig. 3, is a top plan view of the base plate. and showing the basin for receiving wasted oil and the convexed boss therein for receiving and supporting the housing burner and for spreading oil and flame. Fig. 5, is an elevation, partly sectioned, of the device with housing re moved and ready to produce a torch flame.

The horizontally disposed oblong base plate I. is provided on its upper side with a vertical flange 9. which extends longr tudinally of the plate in the form of an ellipse, thereby forming an elliptical shaped basin 3 within the limits of the flange and substantially coextensive with the plate. A boss 4. is formed up centrall of the basin 3. and extends thereabove a di tance adapted for entering the lower end of a housing here inaftcr described. to hold the same in vertical position. The upper end of the boss is Specification of Letters Patent.

cpuvexcd throughout, and the convexed portion is provided with circular openings 5, which are adapted for receiving the lower terminals of a substantially inverted U- shaped pipe (3, having a circular opening 7, in its upper arch communicating with the interior of the pipe and a similar opening 8, in its lower arch communicating with the plpe and registering with the opening 7. Annular flanges l). are formed circumferentially of the lower portions of the terminals of the pipe and are adapted to bear on the convcxed side of the boss 4, and support the pipe in vertical position. The peculiar form of the pi pc 6, combined with the openings? and 8, in the bend thereof, forms a specially contrived gas mixer 10, as will hereinafter be explained. A housing and burner member 11, comprising a circular and vertically extending foot portion 12, which is formed integral with a horizontally disposed elongated oval and elliptical body portion 13, having a convexed bead 14, extending around its peripheral edge and provided with vents or orifices 15, which communicate with the interior of the body portion, is placed to stand vertical in the basin 3, entirely housing the mixer 10, the 4 being entered in the foot portion 12, to hold the housing stable and in )lace. Oritices 16, are formed circumfercntially of the foot portion 19. at intervals and located at points adapted for the passage therethrough of wasted oil from the convexed side of the boss 4. Slots 17, are formed in the lower edges of the foot portion 12. at intervals, for the passage of oil into the basin 3. A boss 18. is formed centrally on the upper side of the body portion 13, of the ousing burner member an provided with a hole 19, which registers with the opening 7. in the mixer. when the parts areoperativciy assembled. A retort 20. columns ing an elliptical hollow member. is provided centrally on its lower side with a boss 21 having a cored extension 22, and is mounted on the upper side of the housing member. the extension 22. being entered in the hole 19, and extending thercthrough and through the intervening space in the housing and into and penetrating the opening 7. in the mixer. to adJaeent the interior of the pipe 6. the boss 21. meanwhile bearing upon the oss 18. and thereby the gas generated in the retort is delivered to the mixer and the re tort held in place. An oil supply pipe 23,

ill

is connected with the one end of the retort, rising vertically in parallelism with the de vice and at a distance therefrom to prevent injury and to be acted on by the flame. The housing member may be turned while in place. to assume any desired position relative to the retort, so that the latter may be sulr jet-ted to the flames in more or less degree.

To use the device, for instance, in a heat ing furnace, the base plate 1, is passed through the feed door of the furnace and laid flat upon the grate bars. the space about the plate being filled by as estos or other suitable filling material, so that air shall be excluded from the device, excepting the air which shall flow in through the pipe 6, the mouths of which are disposed to receive air from the ash pit. The U-shaped mixer member is then mounted on the base in vertical position, the terminal ends of the pipe being entered in the openings 5, in the boss 4, the flanges 9, resting on the eonvexed side of the boss. If it is desired to use the housing burner member 11, to obtain a series of blue flames projected toward the sides of the fire pot, the member mentioned is placed to stand on the base plate, in the basin, the boss 4, being entered into the foot portion of the housing. The retort 20, is then mounted on the upper side of the body portion of the housing or burner, the extension 22, being entered in the hole 19, in the boss 18. The extension 22, extends completely through the upper Wall of the housing member and is entered into the opening 7 in the upper arch of the pipe 6, terminating at a suitable point therein inwardly of the interior of the pipe. The pipe 6, and the eX- tension 22, are provided with capacity for conducting air and gas respectively, in volume suitable for obtaining the proper mixture to produce a combustible gas. The oil supply pipe 23, is then connected with the end of the retort and the oil ermitted to flow into the retort in any suitarle regulated quantity. The retort being cold, the oil will gravitate from the retort through the extension 22, and through the opening or discharge outlet 8, in the lower arch of the pipe 6, into the foot portion of the housing member and upon the eonvexed side of the boss 4, and pass therefrom through orifices 16 and 17, into the basin 3, where the oil is ignited. The burnin oil in the basin will efi'ect a heating of t to device to a degree suiiicient to volatilize the oil, first converting the oil within the foot portion of the housing into a gas which ismixed with air admitted through the. outlet 8, from pipe 6, the gas being vented at the vents 1."), and i nited by flame from the basin, the gas fiiimes thereafter completing the heating of the retort to convert the oil therein into gas. when gas is generated in the retort it is forced to flow through the extension and is projected across the interior of the pipe 6, through and out of the outlet 8. in its transit across the pipe the gas mixes with the air in the pipe and passes into the housing burner member and is vented therefrom at the orifices 15, where ity is ignited and burns, in the well known manner. The multiplicity of small orifices 15, in the periphery of the burner member operates to effect complete combustion of the gas permitted to flow therefrom and, the mixture of gas and air being in proper proportion the vented gas will burn with a blue flame and surmounted by a purplish tip and produce intense heat. When the retort is generating gas the flow of oil to the basin 3, is suspended and the initial priming flame in the'basin is extinguished or dies because of the lack of supply of oil.

If it is desired to use the device for producing a torch flame the burner member is removed and the priming practice mentioned is repeated. In this case the oil will burn in the basin and around the pipe 6, the flames acting directly upon the retort, thereby starting the generating of gas in the retort with promptness. The gas from the retort will flow and mix with air as before mentioned, but it will ignite below the outlet 8, at and about the convexed side of the boss 4. which in this case 0 crates as a spreader, the flames consequent y being present everywhere within the limits of the fire pot of the furnace. The expansive force of the gas operates to effect a rapid flow of the combustible mixture which is deflected by the convexed side of the boss 4. The convertibility of the device is a provision which will allow its use for heating in extreme or moderate temperatures and in many onviromnents. The mobile parts of the device provide means for disposing the retort in various positions relative to the burner member and for prompt and economical installation. The by-prodnets of the retort gravitate the same as the oil and find lodgment at the lower end of the device thereby the retort. and burner are always free of dirt and the like.

Having described my invention what I claim isl. in a gas generating oil burner, the combination of a base plate provided on its up per side with a vertical flange extending in the form of an ellipse and forming with the plate a basin and centrally of the basin with an up-set boss having its upper side formed convex, an inverted U-shaped pipe mounted on said boss and piercing its convexed side, the arch in the pipe being provided transversely in vertical direction with oppositely disposed registering holes, a retort mounted on the arch of said pipe and having a cored extension penetrating the pipe, and a supply pipe connected with said retort.
